Jennifer is saving money to buy a bike. The bike costs $236. She has $124 saved, and each week she adds $16 to her savings. How long will it take her to save enough money to buy the bike?

About a average of 2 weeks

The equation will be written as $236=$16x+$124, where $236 is what she wants to save, $124 is what she already saved, and x is the number of weeks where she adds $16.

So,

$236=$16x+$124

$236-$124=$16x

$112=$16x

$112/$16=x

x=7

She needs exactly 7 weeks to be able to have enough money to get her bike.
